perf tools: Fix build on uClibc systems by adding missing sys/types.h include
Not all libc implementations define ssize_t as part of stdio.h like glibc does since the standard only requires this type to be defined by unistd.h and sys/types.h. For this reason the perf build is currently broken for toolchains based on uClibc, for instance. Include sys/types.h explicitly to fix that. Committer notes: In addition, in the past this worked in uClibc test systems as there was another way to get to sys/types.h that got removed in that cset: tools/perf/util/trace-event.h /usr/include/traceevent/event_parse.h # This got removed from util/trace-event.h in 378ef0f5d9d7f465 /usr/include/regex.h /usr/include/sys/types.h typedef __ssize_t ssize_t; So the size_t that is used in tools/perf/util/trace-event.h was being obtained indirectly, by chance.
